Fit Waist (Stretch)

When this option is at 0%, which is the default, Shale will fit the waistband to the seat circumference, so you can wear the shorts using non-stretchy fabric without an additional opening.

In case you want to use stretchy fabric or add an opening, you can increase the value of this option. At 100%, the waistband will match your approximate body circumference at waistband height.
